Etiquettes and respect for the Quraan

Q: Is it permissible to touch the Quran without wudu?

Q: I have committed a grave sin what can I do now? I was in my office and one colleague asked me to pass her a Quraan from my desk. In order to not let anyone know I'm on my periods, in the blink of an eye I passed it to her with naked hands. I feel cursed now from within... What should I do now as I am afraid of Allah's wrath and anger?

Q: Is it permissible to touch a mus'haf without performing ablution/wudhu? Or let's say is if permissible to study qur'an without wudhu? Because I am memorizing Qur'an and I always go to the comfort room, always pee so I find it hard to make a wudhu every after entering the comfort room. It is also very cold in my country especially in morning. But if it is impermissible or not permissible then I will have no choice but to make wudhu every time after entering the comfort room.

Q: I have recently downloaded the Quraan app on my iPhone (touchscreen). Am I permitted to read and touch the Quraan without wudhu? Also, would it be less beneficial to recite the Quraan in this electronic format rather than in book form?

Q: Can Quran be recited on a cell without wudhu and also off by heart without wudhu?

Q: Can one read Quran on the laptop without wudhu? Not touching the screen but using mouse for (scrolling)?

Q: When I was young, I heard from the person who taught me how to read qur'an, that shaking your leg while sitting shouldnt be done. He said that its not haram but it shouldn't be done because satan does it. Now, everyone I know says they have never heard of this and I can't find anything online. My question is, is it true that you shouldn't shake your leg while sitting?

Q: A muslim brother of mine who is becoming an Alim told me that according to Imam Malik, you are allowed to touch the qur'an under some circumstances without wudhu, reciting the qur'an by touching it and looking inside without wudhu, is this true?

Q: I had a question regarding whether or not one is allowed to read the Qur'an through his phone without wudu? I have the PDF version of the Qur'an on my laptop and I wanted to read it in school. I don't have wudhu all the time so is it possible if I can read the Qur'an through my laptop or phone without wudhu, or is compulsory to have wudhu?

Q: People recite the Qur'an from the phone and watch YouTube or movie on the same phone. So is it right to download the Qur'an on the mobile phone?
